Images display correctly in the gallery (nothing here has changed). However, some (but not all) images upload to anything else incorrectly rotated, be it email, Facebook, Dropbox, etc.
It's like somehow the phone is misinterpreting the orientation of the image when sending it to other apps, even though the gallery view is correct. I've not seen this anywhere else or reported after looking a bit. Is there similar experience out there or a possible solution?
